Description

Technical Field

[0001] This utility model relates to the field of packed tower technology, specifically a separation and environmental protection packed tower. Background Technology

[0002] Packed towers, also known as packed towers, are a common mass transfer device in chemical production. They are often used to treat waste gas and wastewater. Liquid flows from top to bottom along the surface of the packing material, while gas and liquid flow counter-currently, resulting in gas-liquid mixing and achieving separation. However, it is very inconvenient to adjust the density of the packing material after it has been filled into the tower, which wastes a lot of time for the staff.

[0003] For example, patent application number 202322590249.X discloses a chemical packed tower separation device. This utility model discloses a chemical packed tower separation device, which relates to the field of packed tower technology. The device includes a packed tower body, with support columns symmetrically arranged at the lower end of the packed tower body. An air inlet is provided on one side of the packed tower body, an air outlet is provided at the top of the packed tower body, and a water outlet is provided at the bottom of the packed tower body. It also includes a rotating mechanism, a reflux mechanism, and an adjusting mechanism. The rotating mechanism is located inside the packed tower body to allow for more complete contact between water and gas. The reflux mechanism is located on one side of the packed tower body to circulate water. The adjusting mechanism is located below the rotating mechanism and is used to adjust the density of the packing material. This utility model achieves the circulating separation operation of the packed tower by setting a reflux mechanism, setting an adjustment mechanism so that the pressure plate can press the packing material to change the density of the packing material, and setting a sealing door and opening so that the packing material can be replaced. However, when separating viscous liquids, this chemical packed tower separation device will have difficulty mixing and separating the excessively viscous liquid with the gas if it is not broken up, thus affecting the purification efficiency of the separation tower.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a separation and environmental protection packed tower. Utility Model Content

[0005] The purpose of this invention is to provide a separation and environmental protection packed tower to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a separation environmental protection packed tower, comprising a packed tower body, an inlet pipe provided on the upper layer of the packed tower body, and a spray plate provided at the output end of the inlet pipe, a packing layer installed in the middle layer of the packed tower body, and an air inlet pipe provided on the lower layer of the packed tower body, a servo motor installed on the upper surface of the packed tower body, and a drive rod provided at the output end of the servo motor, the drive rod penetrating the surface of the spray plate, and a rotating blade provided on the lower outer surface of the drive rod.

[0007] Preferably, a reducer is provided on the lower end surface of the drive rod, and a support frame is provided on the outer surface of the reducer, and the support frame is connected to the inner wall of the packed tower body.

[0008] Preferably, the output end of the reducer is provided with a rotating rod, and the lower surface of the rotating rod is provided with a rotating plate, and both sides of the rotating plate are provided with support blocks.

[0010] Preferably, the end of the guide slide bar is provided with a scraper, and the scraper is frictionally connected to the inner surface of the packed tower body.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the arrangement of a packed tower body, liquid inlet pipe, air inlet pipe, spraying disc, packing layer, servo motor, drive rod, and rotating blades, allows the rotating blades to break up water droplets when the spraying disc sprays viscous liquid, thereby improving the mixing efficiency of gas and liquid and the separation efficiency of the packed tower. The liquid remaining on the surface of the rotating blades will be thrown to the inner wall of the packed tower body by centrifugal force, avoiding corrosion of the rotating blades.

[0013] 2. This utility model, through the arrangement of a reducer, support frame, rotating rod, rotating plate, support block, guide slide rod, return spring, and scraper, allows the scraper to synchronously contact the inner surface of the packed tower body when the rotating blades rotate, thereby scraping off the liquid remaining on the inner surface of the packed tower body and preventing liquid residue from affecting subsequent separation and keeping the inside of the packed tower body clean. The return spring, through its elastic return characteristic, ensures that the scraper remains in contact with the inner wall of the packed tower body. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1-3 As shown, a separation and environmental protection packed tower includes a packed tower body 1, an inlet pipe 101 is provided on the upper layer of the packed tower body 1, and a spray plate 103 is provided at the output end of the inlet pipe 101. A packing layer 104 is installed in the middle layer of the packed tower body 1, and an air inlet pipe 102 is provided on the lower layer of the packed tower body 1. This technical solution separates and purifies gas or liquid by mixing gas and liquid in the packed tower body 1.

[0021] Furthermore, a servo motor 2 is installed on the upper surface of the packed tower body 1, and a drive rod 201 is provided at the output end of the servo motor 2. The drive rod 201 penetrates the surface of the spray disk 103, and a rotating blade 202 is provided on the lower outer surface of the drive rod 201. With this technical solution, the rotating blade 202 can break up water droplets when the spray disk 103 sprays viscous liquid, thereby improving the mixing efficiency of gas and liquid and improving the separation efficiency of the packed tower. The liquid remaining on the surface of the rotating blade 202 will be thrown to the inner wall of the packed tower body 1 by centrifugal force, avoiding corrosion of the rotating blade 202.

[0022] like Figure 4As shown, a reducer 3 is provided on the lower end surface of the drive rod 201, and a support frame 301 is provided on the outer surface of the reducer 3. The support frame 301 is connected to the inner wall of the packed tower body 1. In this technical solution, the force of the drive rod 201 can be reduced by the reducer 3 to increase the torque of the scraper 307.

[0023] Furthermore, the output end of the reducer 3 is provided with a rotating rod 302, and the lower surface of the rotating rod 302 is provided with a rotating plate 303. Support blocks 304 are provided on both sides of the rotating plate 303. Guide slide rods 305 slide through the surface of the support blocks 304, and a return spring 306 is installed on the outer surface of the guide slide rods 305. In this technical solution, by setting the return spring 306, the scraper 307 can be driven to always be in contact with the inner wall surface of the packed tower body 1 through the elastic return characteristic.

[0024] Furthermore, a scraper 307 is provided at the end of the guide slide bar 305, and the scraper 307 is frictionally connected to the inner surface of the packed tower body 1. With this technical solution, the scraper 307 can be driven to contact the inner surface of the packed tower body 1 simultaneously when the rotating blade 202 rotates, so as to scrape off the liquid remaining on the inner surface of the packed tower body 1, and avoid the liquid residue affecting the subsequent separation and the cleanliness of the inside of the packed tower body 1.

[0025] Working Principle: When using this environmentally friendly separation packed tower, firstly, during purification and separation, gas and liquid are simultaneously injected into the interior of the packed tower body 1 through the air inlet pipe 102 and the liquid inlet pipe 101. If the liquid is too viscous, to improve the gas-liquid mixing and purification efficiency, the servo motor 2 can be simultaneously activated to drive the drive rod 201 to rotate, thereby driving the rotating blades 202 to rotate. The liquid sprayed by the spray plate 103 will contact the rotating blades 202 to break up the liquid before mixing it with the gas, thus improving the filtration efficiency. The liquid remaining on the inner surface of the packed tower body 1 is scraped off by the rotating plate 303, which is decelerated by the reducer 3, causing the scraper 307 to contact the inner surface of the packed tower body 1. This is the working principle of this environmentally friendly separation packed tower.
